What does 'door' mean on a car?
1 Answers
On a car, 'door' refers to the activation mode of the reading light. 'Door' means door, and for the reading light, it means that the dome light will turn on when the car door is opened. If the door is opened or not closed properly, the light will also illuminate, serving as a warning. Its main purpose is to facilitate getting in and out of the car at night. The reading light provides sufficient brightness for passengers when the interior lighting is insufficient, making it convenient for reading inside the car without affecting the driver's normal operation. The reading light is connected to the cigarette lighter socket and can emit lights of different colors when the switch is activated. Currently, there are two types of reading lights in cars: the ordinary reading light (with one bulb) and the LED reading light (with multiple LED bulbs).
